Question 26

Can flight crew change the flight dispatch EEP and EXP status, en-route, if they find another adequate airport? Yes or No.

Answer 26

No

Question 27

During flight planning Sector OMDB-RPLL
Adequate Airports: OOMS, OPKC, VABB, VOPB, VYYY, VTBS, VVDN

During flight, can flight crew change the EDTO status to non-EDTO due to availability of VOMM? Yes or No

Answer 27

No

Determination of whether a flight is EDTO or non-EDTO is established during the dispatch process. The en-route alternate airports nominated at dispatch define the EEP, ETP and EXP for an EDTO flight. This does not change once airborne unless a designated alternate goes below minimums prior to EDTO entry.

Question 28

During Flight Planning, Sector: RPLL-YSSY
EDTO alternates: WABB & YPDN
Adequate Airports: RPMD & YPDN
RPMD does not meet weather minima.

Can this RPLL-YSSY flight be dispatched as EDTO flight with the above conditions? Yes or No

Answer 28

Yes

The EDTO dispatch scenario is valid as there is no requirement for the adequate Airports which define the EDTO Entry and Exit Points for the route to be nominated as EDTO alternates as long as the coverage can be provided by other Airports within the EDTO portion of the flight.

Question 29

Where do we find the flight crew procedures for EDTO?

Answer 29
